TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, JOHN S. HOAR, of West Acton, in the county 'ot' Middlesex, and State of Massachusetts,

have made a new and useful invention having reference to Bench Vises; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying Figure 1 denotes atop, and Figure 2 a bottom view of the jaw of a vise, with my invention applied to it' Figure 3 is an end elevation ;Y and Figureet, 'a transverse section of' the same. In carrying out my invention, I combine with the visejaw A a false adjustable obtuse angle triangular jaw, B, made with a slotted langea,vprojecting back from it. The obtuse augle'a: of the triangular jaw B drawings, of whichbears against the face of the vise jaw, while the flange projects vo ver and rests on the upper'surface of such vise jaw. The slot a', made through the flange, which is semicircular in form, is curved from a centre coincident with the vertex of the obtuse angle -of the jaw B. A hook, C, is passed through the slot, andis hooked upon the flange in its rear, and is secured to the vise jaw A bymeans. of a setfscrew,-b, which screws'in'to the vise jaw, and goes through a slot, c, made in the shank of the hook. The purpose of the hook C and the curved slot ais to hold the jaw B in place inconnection with the jaw A, and to allowthe jaw B to adjust itself laterally, or turn on the vertex of its angle. Ifv desirable, the adjustablejaw Binay have a 'small stud, d, extended from the vertex of it-s obtuse angle, and into a cavity Aor hole, e, made in the vise jaw. The purpose of the adjustable triangular jaw'is to adapt the' vise to holdingan articlewhos opposite sides may be out of-parallelism.

What I claim, is

The adjustable jaw B, made as described. I also claim its combination and arrangement with the vise jaw.

I also claim the arrangement and combination of the slotted hook C, and its set-screw b, with the vise jaw A,'and with the adjustable jaw B, made as described. v

JOHN s'. HoAR.
